IMPROVEMENT I CARBURETERS.

Specification forming part of Letters Patent No. 134,240, dated December24, 1872.

To all whom it may concern:

Be it known that I, JOHN D. AVERELL, of the city, county, and State ofNew York, have invented a new and Improved Carbureter; and that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon making a part of this specification.

This invention is in the nature of an improvement in carbureters; andthe invention consists in arranging within the carbureter a device, ofsiphon form, for allowing the gas and air to escape from the interiorofthe tank, when the same is being filled, in such man- 'ner as toprevent its entering into the room;

also, in surrounding the carbureter with an outer jacket, and fillingthe space between said jacket and the carbureter with Snyders patentnon-combustible cement; .also, in the means of iilling the carbureterand providing `a support for the filling-can; and, finally, in sealingthe upper ends of the several pipes of the carbureter, all of which isfully described fin the following specification:

In the accompanying drawing, Figure lis a sectional view ofinycarbureter, showing the interior tubes, escape-pipes, andnon-combustible iilling; Fig. 2, a plan or top view of same; and Fig. 3,a section, showing cover thrown back and can seated thereon.

Similarletters of reference indicate like parts in the several figures.

A represents the shell or tank of a carbureter, which has a gas-tighttop and bottom. Within the tank A is a partition, B, which is securedwithin the tank in a gas-tight manner. Passing through the top of thetank A is an inlet-pipe, C, and an outlet pipe or riser, D, and also afilling-pipe, a, residuum-pipe b, and capillary supply-pipe c, and asphon escape-pipe, E, the short leg d of which enters just below theunder side of the crown of the tank A, and the longest leg e extendsdownward within the tank through and just below the under side of thepartition B. The curved part of said pipe, which projects above thecrown of the tank, has fitted to it a cock, t. There is also fitted tothe carbureter a oat, f, which is the same as that heretofore patentedby me, and therefore needs no particular description at this time. Thespace F be` low the partition B is the capillary chamber, and it isfitted with a labyrinth wound with cotton-wicking, as in othercarbureters. Surrounding the tank A is a jacket, G, sufficient ly largeto .leave a space between the outer surface of the tank and the innersurface of the jacket; This space is iirmly packed with -anon-conducting material, s, known as Snyders patent non-combustiblecement. To prevent the possibility of leakage of gas or vapor from theends of the pipes a b c, float f, and the siphon escape-pipe E, whenthey pass through the crown of the tank A, I surround said ends withaninverted box, g, and this inverted box with a second inverted box, h,leaving a space, i, between them. This space is then filled with wateror glycerine insuch manner as to allow the edges of a top or holder, k,to enter into said fluid, forming a iiuid seal in the same manner as agas-holder, and ei'ectually preventing the escape of gas from the pipesor joints. Fitting over the seal or holder k is a hinged cover, H,which, when turned backso as to admit of access to the projecting pipes,falls back in a horizontal position, supported by a rest, p.

My carbureter being constructed substantially as above described, itsoperation is as follows: The liquid hydrocarbon is contained in afilling-can, J, of the construction heretofore patented by me. The coverH is thrown back into a horizontal position, and in this way forms asubstantial seat for the can, which is placed upon it. One end of acurved me tallic tube, m, is then secured to the projecting outlet ofthe can, the sealed holder k is removed, and the other end of saidcurved tube is screwed to the end of the iilling-tube a. The hydrocarbonenters through this filling-tube into the tank A of the carbureter, and,as the fluid rises, the gas or vapor from the hydrocarbon, which isabove the iiuid, cs-

capes through the short leg d of the siphon escape-pipe E, the cocktbeing opened, and down the longest lege of said escape-pipe into thecapillary chamber F, and thence through said chamber to the inlet-pipeor riser D, for consumption. Y

The inlet-pipe C, riser D, residuum-pipe b, and capillary supply-pipe c,all being old, both 4. A carbureter, When provided with a hinged coverforming a rest for the llingean, as described..

5. A carbnreter, when combined with a {illing-can and a metallicconducting-pipe, as described.

f 6. In a carbureter, the combination of a fillin g-tube,re'siduum-tube7 and capillary suppl y tube Wit-h a Siphon escape-pipe.
